Self-Locking Rail >> Mature Cow Self-locks

Mature Cow Self-locks are constructed using 2 3/8" OD steel top and bottom rails, and 1 5/8" OD high tensile steel for the vertical and swing bars.

Now even taller - our inside height is 34" to increase cow comfort! The openings are curved so that even bulls can get their heads through the openings.

Artex Self Locks are hot dipped galvanized after fabrication.
